.SPECIFICATION forming part of Letters Patent No.331A73, dated December 1, 1885.

Application led June 17, 1885. Serial No. 168,964. (Model.)

To @ZZ whom it may concern.-

Be it known that I, DENNIs P. BROPHY, of Nokolnis, Montgomery county, Illinois, have invented a new and Improved Mail-Bag-Lock, of which the following is a full, clear, and eX- act description.

The object of my invention is to provide a new and improved mail-bag lock which is strong and durable, safe and reliable.

The invention consists in the combination, with alock-casing having two apertured longitudinal partitions, of bars having lugs which can be passed through the apertures in the partitions, springs acting on the bars, and a top plate having an apertured rib fitting between the partitions of the casing.

The invention also consists in parts and details and combinations of the same, as will be fully set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the Iigures.

Figure lis a face view of my improved mailbag lock. Fig. 2 is a front View, the front plate being removed and parts being in section. Fig. 3 is a longitudinal sectional view of the same. Fig. 4 is a cross-sectional view.

The lock-casing A is provided with the two longitudinal partitions B, each having arecess, C, in its bottom part, at the middle, and a notch, G, extending from the top edge to the recess C. Against the outer edge of the partitions B the locking bars D are pressed by bowsprings E, interposed between the outer sides of the locking-plates and the inner surfaces of the sides ofthe easing. The bars B have locking-lugs F, which are adapted to pass through apertures G in the partitions B, and have beveled ends. Each plate D has a flat lug, H, at its bottom and middle, which lugs have V- shaped recesses H', the recesses of the two lugs facing each other. A pin, K, projects upward from the bottomof the casing, midway between the partitions B, and serves to guide and hold the end of the key L, having two opposite bits, M. The front plate, N, has a longitudinal central rib, O, on its under side, which rib fits between the partitions B and has a series of apertures, l?, for receiving the lugs F on the bars D, and a recess, Q, in its bottom edge at the middle for permitting the bits of the key to turn.. The rib is beveled on its edge. The plate N and rib O have a key-slot, R. On the top of the plateN undercut ribs S are formed for receiving and holding a ticket, T. A sliding plate, U, having one end rabbeted to hold the end edge of the ticket T, as shown in Fig. 3, is provided on its under side with a dovetailed lug, V', which slides in a dovetailed recess, IV, iin the top of the plate N. The plate U has a finger-recess, U. in its top.

The lock-casing A is fastened to one flap, I, of the mail-pouch or other pouch, and the top plate, N, to the other iiap, I. Y

The operation is as follows: The plate N is pressed on the casing A, the rib O passing between the partitions B. The inner beveled edge of the rib O strikes the beveled lugs F, and the same are then forced through the apertures I by the springs E, whereby the two parts of the lock are held together. The slide U covers the key-hole.

To open the lock, the slide U is withdrawn, the key is inserted and given a quarter-turn on its axis. The bits M, acting on. the lugs II, press the bars VD from the partitions B, whereby the lugs F are moved from the rib O, thus permitting the salne and the plate N vt-o be withdrawn.

I do not claim in this application the ticketholding devices, as I propose making the same the subject of a separate application.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a mail-bag lock, the combination, with a casing having apertured longitudinal partitions, of bars having lugs which pass through the apertures in the partition, springs acting on the bars, and of a top plate having an apertured rib on its under side which fits between the partitions in the casing, substantially as herein shown and described.

2. In a mail-bag lock, the combination, with 9 .and the Hat middle lugs, II, the springs E, and

the top plate, N, having the beveled apertured rib @substantially as herein shown and described.
